The #13958 pull request entitled ‘Adding support for PHP 8.3’ has been merged since July 16, and these changes have already been included in release 5.1.1 and 5.2.0.
As opposed to that on Mautic Requirements page it can be read in the Section of ‘Supported PHP versions per Mautic version’ that in the case of both the 5.1 and the 5.2 Mautic versions the latest supported php version is 8.2 only.
I would like to ask for an official statement in this regard. Is it the documentation that would need to be updated, or is it really the case that php 8.3 is not supported at the moment? If the latter, what is the reason behind - as the related issue was successfully closed months ago?
